Reliability and benefit of estimated continuous cardiac output measurement using shunt-side SpO monitor in hemodialysis.

Introduction: Estimated continuous cardiac output (esCCO) is a novel technology that enables non-invasive and continuous monitoring of cardiac output. We compared the concordance in accuracies among esCCO measurements in the shunt limb and non-shunt limb.

Methods: In this single-center prospective observational study, we include Japanese patients who underwent dialysis at our center between April 27, 2021, and February 28, 2023.
